Review Case Reports
Brainstem Congestion due to Dural Arteriovenous Fistula at the Craniocervical Junction: case report and review of the literature1.
Dural arteriovenous fistulas (DAVFs) at the craniocervical junction are rare. Clinical manifestations range from acute or chronic myelopathy to subarachnoid hemorrhage to brainstem dysfunction. We encountered 4 cases of DAVFs at the craniocervical junction with progressive brainstem dysfunction and investigated the typical magnetic resonance imaging (MRI) features using T2-weighting imaging, susceptibility-weighted imaging, diffusion-weighted imaging, and contrast-enhanced imaging. Literature review revealed 10 case reports of DAVFs at the craniocervical junction manifesting with brainstem dysfunction. ⋯ Susceptibility-weighted imaging, diffusion-weighted imaging, or contrast-enhanced scanning should be used during MRI examination of patients with progressive brainstem dysfunction to differentiate DAVFs at the craniocervical junction from other diseases, such as glioma or infection. Prompt diagnosis using MRI is of great significance in producing good functional outcomes of the patients.

Review Case Reports
Denosumab Treatment for a Residual Giant Cell Tumor of the Clivus: A Case Report and Review of the Literature.
Giant cell tumors (GCTs) are a locally aggressive primary bone neoplasm of osteoclast-like cells. These lesions largely occur in the epiphyses of long bones, but there have been rare reports of occurrence in the pelvis, spine, or skull. Of those located in the skull, involvement of the clivus has been rarely reported. ⋯ Denosumab has demonstrated anti-GCT efficacy. In combination with proton therapy, it has the potential to spare a young, vulnerable population from adverse long-term effects of traditional adjuvant radiation therapy. To our knowledge, this is the first report of the use of denosumab in the treatment of GCT of the clivus in the United States.

The aim of this study was to identify potential prognostic factors of hemifacial spasm (HFS) after microvascular decompression (MVD), to establish the appropriate way to tackle postprocedure symptoms and complications (PPSCs), and to find the incidence and duration of PPSCs. ⋯ Although the incidence of PPSCs after MVD is very high, most PPSCs related to cranial nerves recovered spontaneously in several days. Permanent complications after MVD for HFS are rare. Age may relate to the occurrence of PPSCs, and postoperative HFS may be a protective factor for patients with facial palsy after MVD.

To introduce an innovative surgical technique, transvertebral bone graft and augmentation (TBGA), to and evaluate its clinical efficacy in treating osteoporotic vertebral body compression fractures (VCFs), with balloon kyphoplasty (BKP) as a control. ⋯ TBGA is an effective and safe surgical technique that appears to be a promising alternative to BKP for the surgical treatment of osteoporotic VCFs.

The goal of this study was to evaluate the reasons and prognosis of unplanned return to the operating room (URTOR) and to help improve neurosurgical service quality. ⋯ The main reasons for URTOR after neurosurgery were rebleeding and swelling of the brain. The number of URTORs and time from primary craniotomy to URTOR are not associated with morbidity or mortality. However, the seniority of the surgeon affects the rate of URTOR: surgeons with rich experience in surgery may reduce the chance of a second craniotomy and increase the chance of a good prognosis.
